WASHINGTON (AP) — A House committee chairman says President Barack Obama's move to protect millions of immigrants from deportation will encourage more illegal immigration and undermines the Constitution and democratic process.

Republican Rep. Michael McCaul of Texas made the comments Tuesday as he opened a hearing where Homeland Security Secretary Jeh Johnson was defending Obama's controversial move.

In prepared testimony for the House Homeland Security Committee hearing Johnson argued that deferring deportation for longtime residents who aren't deportation priorities anyway is "simple common sense."

Republicans disagree strongly and are trying to figure out the best way to block Obama's executive actions from taking effect.
